TURBOJET ENGINE REACTION NOZZLE WITH BUILT-IN TRUST REVERSER MECHANISM Russian patent published in 2002 - IPC

FIELD: aircraft engineering. SUBSTANCE: proposed reaction nozzle with built-in thrust reverser mechanism has exhaust gas outlet channel in outer fairing, number of hot flaps in lower end of exhaust gas outlet channel, number of cold flaps in lower end of outer fairing, and thrust reverser mechanism. Thrust reverser mechanism consists of two doors which can change position from active one, i.e. thrust reversing position when they form projection in gas stream, to inactive position, i.e. direct thrust position. Doors can be moved off relative to one another at take-off configuration owing to power cylinders acting onto support levers of doors. Invention provides reduction of gas discharge velocity at take-off. EFFECT: reduced noise levels near civil air fields. 7 cl, 7 dwg
